Expansion of vascular volume is of prime importance in the hemodynamic resuscitation of critically ill patients in circulatory shock. Shock is a clinical syndrome representing acute perfusion failure and can be classified into four categories: hypovolemic, cardiogenic, distributive and obstructive. Hypovolemia is most often the cause of shock in the general-medical-surgical hospital. Hypovolemic shock is due to a deficit of vascular volume following the endogenous or exogenous loss of blood, plasma and/or electrolyte fluid. In addition, cardiogenic, distributive, and obstructive forms of shock often are complicated by absolute (extravasation of fluid into the interstitium) or relative (venous pooling) hypovolemia. Thus, volume replacement is usually the single most important intervention in the initial therapy of circulatory shock.
